Detailed implementation manners

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] The outdoor unit of an air conditioner is an important part of the air conditioning system. It is usually installed outside a building, discharges the hot air absorbed by the indoor unit to the outside, and adjusts the indoor temperature through a refrigeration or heating cycle. At the same time, the fan rotates driven by the motor to help air circulation, so that the heat can be dissipated more quickly to keep the normal operation of the outdoor unit. The outdoor unit of an air conditioner is usually installed outside a building and is exposed to the air for a long time, and it is very easy to be attached with impurities such as dust in the air, which will affect the use performance of the outdoor unit of the air conditioner, resulting in a decrease in the refrigeration or heating effect of the air conditioner. Therefore, the present invention proposes an outdoor unit dust-proof device and an outdoor unit of an air conditioner.

[0021] Please refer to together Figures 1 to 3 , the outdoor unit dust-proof device proposed by the present invention includes: A protective frame 1, and a through hollow channel is provided inside the protective frame 1 for sleeving on the outdoor unit body 9; A dust-blocking component 2, the dust-blocking component 2 includes a blocking part located in the hollow channel and an opening and closing adjusting part arranged on the protective frame 1; the blocking part has a switchable open state and closed state, and when the opening and closing adjusting part drives the blocking part to switch to the closed state, it can block external dust from entering the inside of the outdoor unit body 9 through the hollow channel.

[0022] When using this outdoor unit dust-proof device, the staff can sleeved the protective frame 1 on the outside of the outdoor unit body 9. When the air conditioner outdoor unit is idle for a long time, by operating the opening and closing adjustment component, the blocking component can be switched to the closed state, thus effectively blocking external dust and providing dust-proof protection for the air conditioner outdoor unit; when the air conditioner outdoor unit needs to be used, by operating the opening and closing adjustment component, the blocking component can be switched to the open state, making the hollow channel inside the protective frame 1 communicate with the outside world to ensure the normal operation of the air conditioner outdoor unit. The present invention can not only effectively prevent dust from accumulating inside the outdoor unit body 9, but also does not require repeated disassembly and assembly of the dust-proof device, featuring simple operation.

[0023] In a preferred embodiment of the present invention, as Figure 3 shown, the outdoor unit dust-proof device further includes a dust-proof net 805, which is located in the hollow channel and is close to the side of the blocking component away from the outdoor unit body 9.

[0024] The present invention further adds a dust-proof net 805, through which the dust in the air can be effectively filtered and blocked, thereby more effectively preventing external dust from entering the air conditioner outdoor unit and providing better dust-proof protection for the air conditioner outdoor unit.

[0025] It should be noted that the air conditioner outdoor unit is usually installed on the outer wall of a building, with its air inlet side close to the wall and its air outlet side away from the wall. To facilitate the installation of the outdoor unit dust-proof device, the present invention preferably sleeved the dust-proof device on the air outlet side of the outdoor unit body 9. When the air conditioner outdoor unit is idle, the dust-proof net 805 can effectively filter the dust in the air and prevent external dust from entering the air conditioner outdoor unit, thereby enhancing the protection effect against external dust. In addition, in other alternative embodiments, if the dust-proof device is installed on the air inlet side of the outdoor unit body 9, the dust-proof net 805 can continuously filter the dust in the air whether the air conditioner outdoor unit is in operation or not, preventing external dust from entering the outdoor unit and further improving the protection ability against external dust.

[0026] In a preferred embodiment of the present invention, as Figure 3 shown, the dust-proof net 805 is fixed inside the fixed frame 804. The top of the protective frame 1 is provided with an installation slot 801 for the fixed frame 804 to pass through. Two guide rails 802 are provided on both sides inside the protective frame 1, and each guide rail 802 is provided with a sliding groove 803 slidably connected to the fixed frame 804. The top of the fixed frame 804 is provided with a first push-pull handle 806; by pulling the first push-pull handle 806, the fixed frame 804 and the dust-proof net 805 are pulled out of the installation slot 801 so that the staff can clean the dust-proof net 805. Then, by using the sliding connection between the sliding groove 803 and the fixed frame 804, the staff can easily reinstall the fixed frame 804 and the dust-proof net 805 inside the protective frame 1 to achieve the dust-proof function.

[0027] The present invention further realizes the detachable design of the dust-proof net 805, enabling the staff to easily clean the dust-proof net 805, thereby effectively improving the convenience and maintenance efficiency of the dust-proof device.

[0028] In a preferred embodiment of the present invention, as Figure 2 , Figure 4 shown, the blocking member includes a plurality of movable baffles 203, which are arranged vertically in the hollow channel; the opening and closing adjusting member includes: Two adjusting rods 206, movably arranged on both sides of the protective frame 1; Two groups of link mechanisms, arranged on both sides of the plurality of movable baffles 203, and each group of link mechanisms includes a plurality of link mechanisms for connecting the plurality of movable baffles 203 with one of the adjusting rods 206; A second push-pull handle 6, located outside the protective frame 1 and connected to the upper ends of the two adjusting rods 206; by pulling the second push-pull handle 6, the two adjusting rods 206 move upward, thereby driving the two groups of link mechanisms to rotate the plurality of movable baffles 203 upward, realizing the switching of the blocking member to the closed state.

[0029] When the air conditioner outdoor unit is in an idle state, the staff only needs to pull the second push-pull handle 6 to move the two adjusting rods 206 upward, thereby driving the two groups of link mechanisms to rotate the plurality of movable baffles 203 upward, realizing the closing of the blocking member. This design is not only easy to operate but also can significantly improve the protection performance of the air conditioner outdoor unit. When the blocking member is in the closed state, these movable baffles 203 can tightly seal the hollow channel, effectively blocking dust and other sundries from entering the interior of the outdoor unit body 9, thereby protecting it from damage. When the air conditioner outdoor unit needs to be used, the staff only needs to push the second push-pull handle 6 to move the two adjusting rods 206 downward, driving the two groups of link mechanisms to rotate the plurality of movable baffles 203 downward, realizing the opening of the blocking member. At this time, the air circulation is ensured to be smooth without affecting the normal operation of the air conditioner outdoor unit. Through the opening and closing adjusting member with this structure, the staff can easily control the opening and closing of the blocking member, ensuring high-efficiency protection while also taking into account the convenience of use.

[0030] In a preferred embodiment of the present invention, as Figure 4 , Figure 5 shown, a connecting groove 5 for the upper ends of the two adjusting rods 206 to pass through is provided at the top of the protective frame 1, and the upper ends of the two adjusting rods 206 are connected by a first shielding plate 3, and the first shielding plate 3 is used to shield the connecting groove 5 when the blocking member is in the closed state.

[0031] The present invention further considers that when the blocking member is in the closed state, if the connecting groove 5 is exposed, external dust may enter the interior of the protective frame 1 through the connecting groove 5 and then enter the interior of the outdoor unit body 9. In this regard, the upper ends of the two adjusting rods 206 of the present invention are connected by the first shielding plate 3. When the staff pulls the second push-pull handle 6 to switch the blocking member to the closed state, the first shielding plate 3 will move upward synchronously to the bottom notch of the connecting groove 5, thereby blocking the connecting groove 5. In this way, the first shielding plate 3 can effectively prevent external dust from entering the interior of the protective frame 1 through the connecting groove 5, thereby preventing it from entering the air conditioner outdoor unit, further enhancing the protection effect against external dust. At the same time, it can also effectively protect the components (such as the link mechanism, etc.) around the connecting groove 5, thereby improving the practicality and durability of the outdoor unit dust-proof device.

[0032] In a preferred embodiment of the present invention, as Figure 4 、 Figure 5 shown, the upper ends of the two adjusting rods 206 are also connected to the second push-pull handle 6 through the second shielding plate 4, and the second shielding plate 4 is used to shield the connecting groove 5 when the blocking member is in the open state.

[0033] The present invention also connects the upper ends of the two adjusting rods 206 to the second shielding plate 4 and combines with the second push-pull handle 6 to improve the stability of the overall structure. When the staff pushes the second push-pull handle 6 to switch the blocking member to the open state, the second shielding plate 4 will move downward synchronously to the top notch of the connecting groove 5, thereby blocking the connecting groove 5. In this way, the second shielding plate 4 can effectively prevent dust, rainwater and other sundries from entering the interior of the protective frame 1 through the connecting groove 5, effectively protecting the components (such as the link mechanism, etc.) around the connecting groove 5, thereby improving the practicality and durability of the outdoor unit dust-proof device.

[0034] In a preferred embodiment of the present invention, as Figure 2 、 Figure 6 shown, the dust-blocking assembly 2 further includes two limiting members 7 for limiting the two adjusting rods 206 and a third push-pull handle 705 connecting the two limiting members 7. The two limiting members 7 are symmetrically distributed on the top of the protective frame 1. Each limiting member 7 includes a connecting frame 701 arranged on the top of the protective frame 1, an elastic element 702 arranged inside the connecting frame 701, a connecting block 703 connected to the third push-pull handle 705 and the elastic element 702, and a limiting block 704 arranged at the end of the connecting block 703 away from the elastic element 702 and capable of abutting against the second shielding plate 4; by pushing the third push-pull handle 705, the connecting block 703 moves in the direction of compressing the elastic element 702, so that the limiting block 704 is separated from the second shielding plate 4, realizing the release of the limit on the two adjusting rods 206. Among them, the elastic element 702 is preferably a spring.

[0035] The present invention further adds two limiting components 7 and a third push-pull handle 705. By pushing the third push-pull handle 705, the staff can make the connecting block 703 move towards the direction of the compression elastic element 702, so that the limiting block 704 is separated from the first baffle 3, realizing the release of the limit on the two adjusting rods 206. Subsequently, the staff can adjust the two adjusting rods 206 through the second push-pull handle 6 to change the opening and closing state of the blocking component. When the opening and closing state of the blocking component is switched, under the elastic force of the elastic element 702, the connecting block 703 and the limiting block 704 will move towards the direction of stretching the elastic element 702, making the limiting block 704 in close contact with the second baffle 4, thereby limiting the two adjusting rods 206. This design effectively prevents the adjusting rods 206 from accidentally moving due to vibration or other factors during the operation of the air conditioner outdoor unit, thus changing the opening and closing state of the blocking component, and further improving the stability and reliability of the outdoor unit dust-proof device.

[0036] In a preferred embodiment of the present invention, as Figure 4 、 Figure 7 shown, each link mechanism includes a support rod 201 internally connected to the protective frame 1, a first rotating frame 202 connected to the movable baffle 203 and rotatably connected to the support rod 201, a support frame 204 connected to the movable baffle 203, and a second rotating frame 207 connected to the adjusting rod 206 and rotatably connected to the support frame 204.

[0037] When the staff pulls the second push-pull handle 6 to move the adjusting rod 206 upward, the adjusting rod 206 will drive the second rotating frame 207 to move upward. Since there are rotational connections between the second rotating frame 207 and the support frame 204, and between the support rod 201 and the first rotating frame 202, the second rotating frame 207 will make the movable baffle 203 rotate upward through the support frame 204 during the rising process, thereby realizing the closing of the movable baffle 203 and completing the switching of the closing state of the blocking component. On the contrary, when the staff pushes the second push-pull handle 6 to move the adjusting rod 206 downward, the adjusting rod 206 will drive the second rotating frame 207 to move downward. Similarly, through the rotational connections between the second rotating frame 207 and the support frame 204, and between the support rod 201 and the first rotating frame 202, the second rotating frame 207 will make the movable baffle 203 rotate downward through the support frame 204 during the descending process, realizing the opening of the movable baffle 203 and completing the switching of the opening state of the blocking component. The structure of this link mechanism is simple and convenient for maintenance. During the up and down movement of the adjusting rod 206, the opening and closing of the movable baffle 203 are realized through the transmission of the link mechanism.

[0038] Please refer to Figures 1 to 3, the present invention also provides an outdoor unit of an air conditioner, which includes an outdoor unit body 9 and an outdoor unit dust-proof device sleeved on the outdoor unit body 9. The specific structure of the outdoor unit dust-proof device has been described in detail above and will not be repeated here. The outdoor unit dust-proof device equipped with this air conditioner outdoor unit can not only effectively prevent dust from accumulating inside the outdoor unit body 9, but also does not need to be disassembled and assembled frequently, with the advantage of simple operation. This makes the air conditioner outdoor unit more excellent in terms of performance.

[0039] In a preferred embodiment of the present invention, as Figure 3 shown, the outdoor unit dust-proof device is sleeved on the air outlet side of the outdoor unit body 9. Usually, there is more space around the air outlet side of the outdoor unit body 9, which provides convenience for the installation of the outdoor unit dust-proof device. By sleeving the outdoor unit dust-proof device on the air outlet side of the outdoor unit body 9, when the air conditioner outdoor unit is in an idle state, the outdoor unit dust-proof device can effectively block external dust from entering the inside of the outdoor unit body 9 from the air outlet side, thereby ensuring that the performance of the air conditioner outdoor unit is not affected.

[0040] For a clearer understanding, the working principle of the outdoor unit dust-proof device proposed in the preferred embodiment of the present invention during use will be described in detail below with reference to the accompanying drawings.

[0041] Please refer to Figures 3 to 7 together. When using this outdoor unit dust-proof device, the staff first sleeved the protective frame 1 on the air outlet side of the outdoor unit body 9. Then, the staff pulled the connecting block 703 forward through the third push-pull handle 705, so that the connecting block 703 drove the limit block 704 to move forward from the bottom of the second baffle 4. Subsequently, the staff pushed the adjusting rod 206 downward through the second push-pull handle 6, so that the adjusting rod 206 drove the second rotating frame 207 to move downward. Through the rotational connection between the second rotating frame 207 and the support frame 204, and the rotational connection between the support rod 201 and the first rotating frame 202, while the second rotating frame 207 moves downward, it drives the movable baffle 203 to rotate downward through the support frame 204, thereby opening the movable baffle 203. At the same time, the second baffle 4 moves to the top notch of the connecting groove 5 for protection to ensure that the outdoor unit body 9 can work normally.

[0042] When the outdoor unit body 9 is not used for a long time, the staff can pull up the adjusting rod 206 through the second push-pull handle 6, so that the adjusting rod 206 drives the support frame 204 to move upward through the second rotating frame 207, and then the movable baffle 203 flips upward and closes, ensuring that the movable baffle 203 can effectively block external dust. At the same time, the first baffle 3 moves to the bottom notch of the connecting groove 5 for protection. Moreover, in the limiting member 7, the elastic force of the elastic element 702 will push the connecting block 703 and the limiting block 704 to move backward, so that the limiting block 704 limits the second baffle 4, thereby limiting the adjusting rod 206.

[0043] In addition, when the outdoor unit body 9 is not used for a long time, the dust filter net 805 will filter and block the dust in the air, further preventing dust from entering the interior of the outdoor unit body 9. The staff can pull out the fixing frame 804 and the dust filter net 805 from the middle of the installation groove 801 through the first push-pull handle 806 to clean the dust filter net 805. Then, through the sliding connection between the sliding groove 803 and the fixing frame 804, the staff can install the fixing frame 804 into the interior of the protective frame 1 again to continue the dust prevention work.
